About

System design practice should feel measurable.

SystemRound is built for engineers preparing for system design interviews who need more than generic prompts and broad advice. The product turns each attempt into reasoning-aware feedback, skill diagnosis, and a focused next practice step.

Product principles

Practice should produce a diagnosis, not just a score.
Feedback should explain the reasoning gap and the lesson that fixes it.
Rubrics should be authored around real system design signals: requirements, estimates, APIs, data, reliability, scale, and trade-offs.
Problem walkthroughs should reward defensible choices, not memorized architecture diagrams.

Content standards

Every problem is structured into stages so candidates can improve one part of the answer at a time.
Rubric language is written to identify observable evidence and design reasoning, not vague impressions.
Lessons and blog posts link back into practice so reading turns into a retry loop.
AI-assisted feedback is treated as an evaluation layer on top of authored rubrics, not a replacement for product judgment.

A full curriculum behind the grade

The Delivery Framework, 34 lessons, 17 patterns, and 14technology deep dives are authored to the same standard as the rubrics — so every diagnosis points to real depth, not a one-line tip.
